Patent FR-2477803-A1 (FR)
Inventor: SHIGERU KOGURE
IPC: H03H9/215
Filed: 1981-02-24
Abstract: A mode coupled tuning fork type quartz crystal vibrator utilizing two different vibrational modes is provided. The vibrator includes at least one electrode on each tuning fork arm for adjusting the resonant frequency of the main vibration and an electrode for adjusting the frequency-temperature characteristic of the vibrator. The main vibration is in the flexural mode (F1) and the sub-vibration is in the torsional mode (T0). The resonant frequency of the first overtone in the flextural mode is designated by fF and the resonant frequency of the fundamental vibration in the torsional mode is denoted by fT. The difference between fF and fT defined as  DELTA f=fF-fT determines the frequency-temperature characteristics of the mode coupled vibrator. The electrodes for adjusting fF are substantially triangular in shape and the electrodes for adjusting fT are substantially rectangular in shape. These electrodes are disposed at positions near the top of each tuning fork arm and on both principal surfaces of the vibrators. The resonant frequencies are adjusted by removing a portion of electrode material or adding a strip of metal to the electrode. Preselected oscillation frequency and frequency-temperature characteristics in the form of a cubic curve at ambient temperatures are obtained by first adjusting  DELTA f to a preselected value  DELTA fO and then adjusting fF to a preselected value fF0 at the same time maintaining  DELTA f at the value  DELTA f0.

The harvested material to be sepd. is fed on to one end of the screen and grapeless stalks discharged at the other end. The material is pref. conveyed along the screen by its vibratory action which follows an oscillatory, inclined path with the upper end inclined towards the discharge end of the screen. The screen is pref. supported on resilient mountings set between surfaces parallel to the oscillatory path of the screen. The vibratory mechanism pref. comprises a rotary eccentric with connecting rod which is parallel to the oscillatory path when the top dead centre position is reached. The machine removes grapes much more effectively and with less damage than previous machines. Prod. quality is comparable to hand removal while machine output is achieved.

Title: Electric envelope opener for high handling capacity - uses cylindrical or burning cutters to cut along one edge and two sides of envelopes stored in magazine
IPC: B43M7/00
Filed: 1981-09-08
Abstract: Envelopes to be opened are placed manually in a magazine comprising an inclined plane to raise them to a slowly rotating cylinder. The cylinder is rotated by a stepper motor to project the letters onto a cutting block (17) where they lay in a horizontal position. A slot allows a circular cutting saw or burning type cutter to make an incision. The envelope is held in position by suction from within the block by use of a tube. The envelope is then conveyed to a table where it slides under a metallic tongue. A photocell controls operation of pulley wheels above the envelope to project it to cutting blocks at right angles to the first block. Two parallel cuts are made to join up with the first cut to allow the contents to be extracted.

Patent FR-2494463-A1 (FR)
Inventor: BECK NICHOLAS JOHN
IPC: G05D7/01
Filed: 1981-11-17
Abstract: The flow control valve is used for controlling the water flow for an instantaneous water heater in order to compensate changes in the water pressure in the mains and the effect of changes in the position of the outlet, for example a shower attachment. The flow control valve has a housing (1), which accommodates a valve spool (6) connected to a spring-loaded diaphragm (9) in a differential chamber (12). The spool valve controls the flow from an inlet, via a valve seat (7), to an intermediate chamber (8) and as far as an opening (20) controlled by an adjustable valve plate (21) of special cam form which can be set in such a way under the control of a rotatable spindle (23) that the desired outlet flow rate through an outlet chamber (19) is set. Connected to the intermediate and outlet chambers is a small, continuously open channel. A small hole (31) leads from the outlet chamber to and through the hollow interior of the valve spool and into the differential chamber (12). The valve spool is subjected to the compensation movements of the diaphragm and maintains a constant flow as preset by the position of the valve plate (21) in accordance with the choice of the user. Certain alternative or modified arrangements are described.
